"It is important to note that the scale of investments being made by these cloud providers is dwarfed by actual cloud revenue. For example, Azure from Microsoft generates $25B in revenue a quarter. The ~$10B OpenAI investment by Microsoft is roughly 6 weeks of Azure revenue. This suggests the cloud business (at least for now) is more important than any one model set for Azure."
The most interesting implication in the short term is that the impact of model availability on cloud provider choice is more important than the models themselves. Will organizations choose Azure because it offers GPT-4, or AWS because it offers Claude?
This also explains reciprocal VC structures whereby e.g. Amazon invests billions in Anthropic while Anthropic in turn promises to spend billions on AWS cloud resources. Anthropic gets a higher valuation and broader distribution, while AWS gets more customers. It would be a fascinating outcome if the predicted oligopoly in fact ends up as several exclusive partnerships.
